Oxidant sensor

Claim 1

AN OXIDANT SENSOR COMPRISING: AN OPEN CONTAINER HAVING A REACTIVE ELECTROLYTIC SOLUTION OF HALIDE IONS DISPOSED THEREIN; A CAP MEMBER SUPPORTED BY SAID CONTAINER; AN OUTER TUBULAR MEMBER HAVING AN UPPER END COUPLED TO AND ENCLOSED BY SAID CAP MEMBER AND HAVING A LOWER END EXTENDING DOWNWARD INTO SAID SOLUTION, SAID OUTER TUBULAR MEMBER HAVING AN OPENING IN ITS OUTER SURFACE ADJACENT SAID OPEN LOWER END; A SLEEVE MEMBER HAVING AN UPPER END COUPLED TO AND ENCLOSED BY SAID CAP MEMBER TO EXTEND A LOWER END DOWNWARD INTO SAID CONTAINER, SAID SLEEVE MEMBER BEING POSITIONED LATERALLY WITHIN SAID OUTER TUBULAR MEMBER, SAID SLEEVE MEMBER HAVING UPPER AND LOWER END SECTIONS, SAID UPPER END SECTION HAVING A GREATER CROSS SECTION THAN SAID LOWER END SECTION, SAID UPPER END SECTION HAVING AN OPENING IN ITS OUTER SURFACE; AN INNER TUBULAR MEMBER EXTENDING THROUGH SAID CAP MEMBER AND EXTENDING DOWNWARDLY INTO SAID CONTAINER WITHIN SAID SLEEVE MEMBER FOR FIRST BUBBLING A FLUID CONTAINING UNKNOWEN AMOUNTS OF A PRIMARY OXIDANT INTO SAID REACTIVE SOLUTION AND THEN UPWARD ALONG SAID OUTER SURFACE THEREOF TO DEFINE A PREDETERMINED FLUID PATH WHEREBY SAID PRIMARY OXIDANT IN CONTACTING SAID SOLUTION REACTS TO COMPLETION WITH SAID HALIDE IONS TO GENERATE THE CORRESPONDING HALOGEN AS AN INTERMEDIATE OXIDANT WHICH BUBBLES WITH SAID FLUID ALONG SAID PREDETERMINED PATH; A CATHODE ELECTRODE OF A NOBLE METAL UNREACTIVE WITH SAID ELECTROLYTIC SOLUTION, SAID CATHODE BEING PARTIALLY IMMERSED IN SAID SOLUTION AND MOUNTED UPON THE OUTER SURFACE OF SAID INNER TUBULAR MEMBER IN SAID PREDETERMINED FLUID PATH; AND MEANS INCLUDING AN ANODE ELECTRODE CLOSELY ADJACENT SAID CATHODE AND IMMERSED IN SAID SOLUTION FOR POLARIZING SAID CATHODE ELECTRODE SUCH THAT SAID CATHODE ELECTRODE IS DEPOLARIZED IN RESPONSE TO SAID FLUID CONTAINING SAID INTERMEDIATE OXIDANT, THEREBY ALLOWING A CURRENT TO FLOW BETWEEN SAID CATHODE AND ANODE ELECTRODES IN DIRECT PROPORTION TO SAID AMOUNT OF PRIMARY OXIDANT ORIGINALLY PRESENT IN SAID FLUID.
